Periapical radiograph designed to show tissues around the apical area of the tooth

Radiology and Radiography is an aspect of medicine that uses radioactive substances, sound waves, and electromagnetic radiation to diagnose and to treat various diseases. Radiology is just a branch of medicine like internal medicine, dermatology, immunology, and others that requires someone who wants to study it to pass through a process of training in the medical school. And such a person should be ready to pass the American Board of Physician Specialties (ABPS) examination before he can be licensed to practice. Radiography, on the other hand, is the process of making radiographs, that is, images produced by radiation from instruments like X-ray to analyze and examine different parts of the body. Radiography helps in giving information to a medical practitioner to successfully diagnose a patient. Radiographs are very important to radiologists, and most times they rely on radiography to give adequate information about the conditions of their patients and possibly the necessary treatments they need to take

Alpha particles and beta particles are example of Particulate Radiation while Cathode rays are beams of electrons in a partially evacuated glass tube with a potential difference between an embedded cathode and an anode. X-rays are very short wavelength e.m. radiation, produced when electrons with energy above a few keV strike a heavy target (say tungsten).

I think the answwer is wrong cuz, isnt the cathode negatively charged???

The answer to this is letter B. There are some people who have not heard of Pulmonary Edema. This is a type of condition wherein fluid starts to fill up the tissues and the air spaces of the lungs. This can be a fatal condition especially since it can cause the heart to work harder which can lead to cardiac arrest. People who have congestive heart failure may be more prone to getting this condition. Another possible cause is when one of the ventricles of the heart cannot pump blood properly. People who are suffering from this condition would need to get medical treatments immediately so that their lives can be saved.

Colonic InterpositionThis is where the feedback should go. Need feedback.

1. Protect the film from exposure to light and saliva

The correct answer to this question is C, 2, and 3 only. This fracture is popularly known as a broken wrist. WIth Colles fracture, the radius bone of the forearm is completely fractured. With this fracture, the radius is displaced and shows a visible deformity. While it is guaranteed the radius bone will be fractured, it is only a possibility of the ulnar being fractured. It is a common fracture. Colles fracture is named after Abraham Colles. He was an Irish surgeon. He was the first to describe the fracture and did so in 1814. Abraham Colles described it by merely looking at an X-Ray.

MRI

Bad photomultiplier tube A: Image indicates that the photomultiplier tube positioned behind the scintillator is bad and therefore shows non-uniformity in the shape of photomultipler tube.

Brain abscessesA: Primary CNS Lymphoma can produce lesions with reduced ADC values however it generally enhances homogeneously in the immunocompetent patient (suggested by previously well history). Thin walled enhancement would also be unlikely with lymphoma and it is not the best answer. B: Multiple thin walled ring enhancing lesions with edema and reduced ADC values are most suggestive of abscess which is the best answer. This was confirmed on subsequent stereotactic aspiration. C: Multifocal bilateral noncontiguous tumors would be unlikely. They would not likely have a uniform wall thickness without a mural nodule. They would not have reduced ADC values. D: Metastatic neuroblastoma is nearly always extradural and calvarial based. Intraaxial lesions are rare and would not likely enhance in a thin ring like fashion.
